[QUOTE="WayneF, post: 217008, member: 12496"] ? There is no sensor. TTL uses the hot shoe communication, called CLS today. Camera requests a preflash, and meters it, and then communicates again via hot shoe to set the flash power level. The unit possibly might flash on hot shoe, but on DSLR, the flash power level will be undetermined and is not controllable. It has no manual mode. ? The flash is only a flash if it can do Manual mode for the trigger. My bet is that this one cannot. Instruction manual makes no mention of any Manual mode. I see it say 7.55 volts there, but these numbers are really just random hearsay by parties that may or may not know what they are doing. If you really want to know, you better measure yours yourself. And the Wein SafeSync costs $50, money better invested in a more current flash, IMO. Even if otherwise, the warning is possibly true and important and needed on some cameras, but the Nikon DSLR is rated to handle up to 250 volts sync voltage. This is in all the Nikon DSLR camera manuals, section OPTIONAL FLASH UNITS (SPEEDLIGHT), where it says "Use only Nikon flash accessories". Or search the PDF manual for "250 V". 34 volts is higher than todays norm, but is still nothing, not a concern. 300 volts would be a concern. :) But this one flash has no compatible mode anyway (no manual flash mode either).
